Implementation of a Finger Skin Temperature Stress Evaluation System for Prolonged Driving

長期單調的駕駛行為會降低駕駛者的警覺性，增加駕駛的壓力，會導致發生交通事故的機率升高。一個可行的解決方法是發展一套利用生理參數評估駕駛壓力的技術，應用在汽車上，過去有人做過相關的研究，使用心電圖來評估駕駛的壓力，但準確性易受干擾，且靈活性較低。我們使用手指皮膚溫度當作生理參數,具有以下優點：非侵入式、便利、可持續偵測，利用這些優點，我們希望能發展一套駕駛者的壓力評估系統。我們利用不同的手指溫度變化，做為指標，來判斷駕駛的壓力狀態，希望能降低發生事故的風險。我們的研究結果顯示，我們的系統具有準確性以及可行性，可以準確判斷駕駛的壓力狀況。本系統具有高度的靈活性、準確度高、重量輕、成本低廉等優點，可以應用在汽車上，減低發生交通事故的風險。

Prolonged monotonous driving may lower driver awareness and increase driver stress, which may result in increased traffic accident risk. Studies have used electrocardiogram signals to assess driver stress, but accuracy is susceptible to interference and this method is less flexible. Using finger skin temperature as a physiological variable is noninvasive, convenient, and sustainable. This study uses skin temperature as a possible indicator of driver stress to reduce the incidence of potentially dangerous situations. Results show that the system is feasible and accurately determines driver stress. The system is flexible, accurate, low cost, lightweight, and can be used in cars to reduce traffic accident risk.
